The old things I repaired have become fine

Chapter 33: Was this lightning-struck jujube wood struck by nuclear power?

Generations of cultural relics restorers have accumulated considerable experience in cleaning such dirt.

For copper rust, for iron rust, for rust buried in the soil, for rust soaked in sea water...

They are classified into different categories, each with its own solution, and there are a lot of papers accumulated.

Of course, Shen Le does not have the conditions to test the stains now to see whether they have a high salt content or a high alkali content, and he cannot do any electron energy spectrum analysis (EDS), X-ray diffraction analysis (XRD), infrared spectrum analysis (IR) or the like.

For now, he had no choice but to use the most basic method, try it bit by bit, and see which method was more effective.

Shen Le put down the flashlight, took a needle, carefully probed into the crack, and first picked out a little dirt from the crack.

Then, he arranged several bowls and placed different types of reagents in them:
Diluted white vinegar...

Diluted baking soda...

Diluted caustic soda solution...

Alcohol……

acetone……

Throw a little dirt into each bowl and observe their ability to dissolve dirt. After throwing everything, look left and right and sigh:

"I need a cement house... I need a cement house... Acetone is too dangerous to keep in a wooden house. It is flammable, explosive, and volatile!"

Although he had tried his best to be careful and placed the acetone and the bowl containing the acetone in separate iron basins, even if a little bit was spilled out, it would not catch fire on the spot.

But this crap will evaporate, and there are special methods for storing and treating the waste liquid. You can't just dump it down the drain!
Shen Le muttered to himself as he opened his notebook and added another long-term task to himself. Then, he moved the dirt in the bowl one by one and observed how it dissolved in the solvent:

"Ah, acetone is indeed the most efficient. Oh, I have to take the risk again and deal with this thing..."

He dipped a cotton pad in acetone, held his breath, and dripped one drop after another into the dirty wood cracks. He watched the liquid gently seep into the wood cracks until there was nothing left. He then covered the wood cracks with the wet cotton pads and waited for the dirt to slowly dissolve.

Then, he quickly opened the window and door and rushed out of the studio:

"Oh! Xiaoling, don't go in! There are flammable items in there, be careful not to catch fire!"

How can you rush in with the door open? Those who know are puppets, and those who don’t think you are a cat!
He tucked the puppet under his armpit and carried it across the yard, then took off his gloves, washed his hands, and breathed in fresh air. Then he took out his phone and quickly placed an order for an industrial dust mask.

The kn95 mask can block dust, but it cannot block the vapor of organic solvents!
For the sake of your own life and health, you should try to breathe less of this kind of thing!

"Leaving the school laboratory and working at home, the working conditions are too difficult... I miss school, I miss the school's equipment and instruments, and I think I may need a fume hood..."

"But this thing is so expensive, is there any way to make one by hand..."

It is impossible to get a fume hood immediately. Even if you rub it by hand, it will not be made so quickly - after all, you can saw the wood boards yourself, and it is not difficult to buy glass. But the most important exhaust fan still needs to be found.

For the time being, Shen Le still had to carry on with his body and acetone.

After a while, he would peel off the cotton pad, look at the stains on it, and estimate the speed of the dirt leaching out. When he saw that it had almost leached out, he would wipe it with cotton wool, then wrap clean cotton wool around the needle, and rub it deep into the cracks little by little.

After wiping, rinse it again and then take it outside to dry. Let the acetone evaporate naturally, and let the soaked wood dry naturally in the shade, shrinking slowly, but not shrinking too violently to create some cracks.

"Fortunately, this wood is not very hard, so it doesn't take too long to dry in the shade. If it were hardwood, it would take a long time..." Softwoods like pine and fir can be dried in the shade in just three to six months. Hardwoods like sandalwood and golden nanmu may not be completely dried in the shade in a year.

If it is a giant tree like the golden nanmu pillars in the Forbidden City in Beijing, with a diameter of more than one meter, it would be even more incredible. It would basically be impossible to destroy it without three to five years.

Even if this ink fountain has only been washed a few times, it does not need to be dried in the shade for half a year like newly cut wood before it can be used to make things, otherwise it will crack directly. This cannot be done in an hour or two.

It takes time to wait for the wood to dry in the shade, and since he has nothing to do anyway, Shen Le turned back and continued to think about the ghost ball.

Brother, regarding the material of the ghost ball, the Forestry Research Institute has already completed the experiment and has given the first feedback. The answer is simple, just two words:

Jujube wood.

"Well, one is a date tree, and the other is also a date tree..."

Shen Le muttered as he searched the mansion, but sure enough, he couldn't find any ready-made jujube wood that was suitable for use.

Whether it was the workbench he dragged over or the door latch at the entrance of the mansion, these parts that he had high hopes for were not made of jujube wood, so a small piece could not be sawed off to repair the ink fountain.

Then go to the almighty Taobao for help...

"No, how come there are lightning-struck jujube wood on Taobao? And over 100 of them have been sold? How can such a thing be mass-produced?!"

Shen Le struggled for a while, but couldn't figure it out. He scrolled down and found a question in the comments:

"Was it split by nuclear power? Hydropower is too negative, the effect is not good!"

This... everyone has a lot of imagination...

“What is nuclear power?”

Her knees felt heavy, and Xiao Ling jumped up again, staring at the computer screen with sparkling eyes. She looked at it for a long time, and even jumped onto the desktop and reached out to grab his mouse:

"What do you want to buy? Do you want to buy me clothes?"

Shen Le sighed, opened the shopping cart on Taobao, and clicked on the page to show her:
"Option 8: Buy a jujube wood stick 2 cm long and 8 cm in diameter, and then cut it into a round bead by hand. It costs yuan and takes hours... I don't think I can cut a ball in three days."

"Option 8: Buy the wood, which costs 1258 yuan. Then buy a mini woodworking lathe, which costs yuan. It's a one-time solution. In the future, you don't have to do manual work when turning anything made of wood."

"Choose three, buy a jujube wood bracelet with a diameter of 1.8 cm, which costs 30 yuan. Xiaoling, which one do you think I should choose?"

"Of course I'll choose the expensive one!" Pinocchio answered without thinking. Shen Le rubbed his brows in annoyance:
"But if you choose the expensive ones, I won't have money to buy you clothes for the time being!"

"That won't work!... Let's just buy a bracelet!"

Good, good... Fortunately, I didn't choose the first one. Otherwise, I would have to buy clothes, and I wouldn't mind working myself to death -

This is truly a great filial piety!
